背景技术Background technique
大气污染是我国目前最突出的环境问题之一。其中工业废气是大气污染物的重要来源。工业废气中最难处理的就是有机废气，主要包括各种烃类、醇类、醛类、酸类、酮类和胺类等。它们主要来源于石油和化工行业生产过程中排放的废气，特点是数量较大，有机物含量波动性大、可燃、有一定毒性，有的还有恶臭。国内橡胶厂、再生胶厂等橡胶相关行业在生产过程中也会产生大量的有机废气。这些有机废气除了造成直接的大气污染外，还会在大气中参与复杂的反应生成二次污染物，成为PM2.5的主要来源之一。所以有机废气的处理与净化问题亟待解决。Air pollution is one of the most prominent environmental problems in my country at present. Among them, industrial waste gas is an important source of air pollutants. The most difficult to deal with in industrial waste gas is organic waste gas, which mainly includes various hydrocarbons, alcohols, aldehydes, acids, ketones and amines. They mainly come from the waste gas emitted during the production process of the petroleum and chemical industries. They are characterized by large quantities, large fluctuations in organic matter content, flammability, certain toxicity, and some have a foul smell. Domestic rubber factories, reclaimed rubber factories and other rubber-related industries also produce a large amount of organic waste gas during the production process. In addition to causing direct air pollution, these organic waste gases will also participate in complex reactions in the atmosphere to generate secondary pollutants, becoming one of the main sources of PM2.5. Therefore, the treatment and purification of organic waste gas needs to be solved urgently.
目前对于有机废气净化处理手段主要包括：直接高温燃烧法、催化氧化法、臭氧除臭法、活性炭吸附法、酸碱药液喷淋法、生物除臭法等。这些方法在不同程度上存在设备投资高、运行成本高、处理气量小、工作不稳定、占用空间大、脱臭净化效率不高、存在二次污染等问题。目前新型的紫外线废气处理系统得到了越来越多的应用，通过紫外线处理后的大分子有机废气的分子链被打断变成小分子污染物，再经过后续设备的处理可以将废气的排放降低到一个很低的水平。但是这些紫外线设备还普遍存在一个问题就是智能化控制水平很低，不能根据污染物浓度实时控制紫外线设备的处理功率，从而造成能源的浪费或者污染物处理不达标的问题。另外经过紫外线设备处理后的废气在排放时因为传统湿法后处理设备(一般采用洗涤塔)的局限性还会造成污染物随气体中水雾流动排放造成的二次污染问题，尤其是与PM2.5的形成有很大关系。At present, the purification and treatment methods of organic waste gas mainly include: direct high-temperature combustion method, catalytic oxidation method, ozone deodorization method, activated carbon adsorption method, acid-base liquid spray method, biological deodorization method, etc. These methods have problems such as high equipment investment, high operating cost, small processing gas volume, unstable work, large space occupation, low deodorization and purification efficiency, and secondary pollution to varying degrees. At present, the new ultraviolet exhaust gas treatment system has been applied more and more. The molecular chain of the macromolecular organic waste gas after ultraviolet treatment is interrupted and turned into small molecular pollutants, and then the exhaust gas emission can be reduced by subsequent equipment treatment. to a very low level. However, there is still a common problem in these ultraviolet equipment, which is that the level of intelligent control is very low, and the processing power of ultraviolet equipment cannot be controlled in real time according to the concentration of pollutants, resulting in the waste of energy or the problem of substandard pollutant treatment. In addition, the exhaust gas treated by ultraviolet equipment will also cause secondary pollution caused by the discharge of pollutants with the flow of water mist in the gas due to the limitations of traditional wet post-treatment equipment (generally using scrubbers), especially with PM2 The formation of .5 has a lot to do with it.

如图2所示，光氧裂解柜4内还设有用于安装单片机系统的智能控制柜9；光氧裂解柜4包括按照间距和数量均匀分布的高能紫外线灯组模块6和臭氧供给模块7，所述臭氧供给模块7位于高能紫外线灯组模块6之后；高能紫外线灯组模块6、臭氧供给模块7的灯组模块之间设有TiO2催化网。本实施例中高能紫外线灯组模块采用254nm波长+185nm波长双波段高效紫外线灯来处理废气，一是应用紫外线灯UVD185nm波段紫外线条件下O2自身反应生成氧离子和臭氧O3来氧化还原反应废气，二是利用254nm波段紫外线的高能来裂解有机废气，三是利用254nm紫外线照射涂有TiO2的催化网产生-OH来氧化有机废气。湿度影响TiO2催化网的催化效率，TiO2表面亲水,对水强烈吸附,当水含量增大时,水分子与甲苯分子在TiO2表面吸附竞争,阻碍甲苯分子在催化剂表面活性位的吸附,使得表面反应速率下降，因此，本实施例中通过除湿过滤网的设置，对废气进行滤湿处理。As shown in Figure 2, the photo-oxygen cracking cabinet 4 is also provided with an intelligent control cabinet 9 for installing a single-chip system; the photo-oxygen cracking cabinet 4 includes high-energy ultraviolet light group modules 6 and ozone supply modules 7 evenly distributed according to spacing and quantity, The ozone supply module 7 is located behind the high-energy ultraviolet lamp group module 6; a TiO2 catalytic net is arranged between the high-energy ultraviolet lamp group module 6 and the lamp group modules of the ozone supply module 7 . In this embodiment, the high-energy ultraviolet lamp group module adopts a dual-band high-efficiency ultraviolet lamp with a wavelength of 254nm + 185nm to treat exhaust gas.One is to use the ultraviolet lamp UVD185nm band ultraviolet condition. , The second is to use the high energy of ultraviolet light in the 254nm band to crack organic waste gas, and the third is to use 254nm ultraviolet light to irradiate the catalytic network coated with TiO2 to generate -OH to oxidize organic waste gas. Humidity affects the catalytic efficiency of the TiO2 catalytic network. The surface of TiO2 is hydrophilic and strongly adsorbs water. When the water content increases, water molecules compete with the adsorption of toluene molecules on the surface of TiO2 , hindering the adsorption of toluene molecules on the active sites of the catalyst surface. , so that the surface reaction rate decreases.
